8afdf4f146 node: podresources: translate types in cm
during the review, we convened that the manager types
(CPUSet, ResourceDeviceInstances) should not cross the
containermanager API boundary; thus, the ContainerManager layer
is the correct place to do the type conversion

We push back the type conversions from the podresources server
layer, fixing tests accordingly.

ad68f9588c node: podresources: make GetDevices() consistent
We want to make the return type of the GetDevices() method of the
podresources DevicesProvider interface consistent with
the newly added GetAllocatableDevices type.
This makes the code easier to read and reduces the coupling between
the podresourcesapi server and the devicemanager code.

No intended changes in behaviour, but the different return types
now requires some data massaging. Tests are updated accordingly.

1375c5bdc7 node: podresources: make GetCPUs return cpuset
a upcoming patch wants to add GetAllocatableCPUs() returning a cpuset.
To make the code consistent and a bit more flexible, we change the
existing interface to also return a cpuset.
